It is squared because the consumer is two levels from the primary producers. The formula that I used for the problem was: (Energy required) / (Efficiency)^n
Where n = how many levels from the primary producers you are. Also make sure you convert % to decimal or fractional form.
I wish you the best of luck tomorrow, Kevin!
